IP Leadership for Transactions, Financings, and Acquisitions. Dr. Polizzi’s practice also includes due diligence evaluation and counseling in the context of venture investment assessments and in connection with public and private financing, spin-offs, partnerships, and mergers and acquisitions, where her IP strategies have helped drive the value of multibillion dollar deals. Representative transactions resulting from Dr. Polizzi’s leadership include the $14 billion acquisition by Pfizer of client Medivation, as well as the previous $225 million Pfizer investment in Medivation; Myriad Genetics' $375 million acquisition of Counsyl, Inc.; Celgene Corporation’s $9 billion acquisition of client Juno Therapeutics and earlier $2.9 billion acquisition of client Abraxis BioScience. Dr. Polizzi was retained by both Pfizer and Celgene for ongoing patent strategy and counseling work on the existing patent portfolios and with expanded representation of the parent companies following these acquisitions. Other representative transactions where her astute leadership has proved invaluable include Shiseido’s acquisition of client Olivo Laboratories; Pfizer’s acquisition of client Rinat Neuroscience; Alpine Immune Sciences’ $48 million Series A financing and subsequent $90 million merger with Nivalis Therapeutics, resulting in a publicly traded company; SQZ Biotech’s $72 million Series C financing; and Lyndra Therapeutics’ $55 million Series B financing.

Select Representations

Dr. Polizzi is patent counsel to numerous publicly traded and privately held companies, with many new client relationships resulting from her strong reputation in the life sciences industry. A selection of her representative matters include the following:

Genentech, the world’s first and most successful biotechnology company, relies on Dr. Polizzi’s strategic patent counseling and prosecution services for its most difficult and challenging patent matters. Her work involves developing overall patent strategy, patent application drafting, and prosecution for key technologies. Her high-value work for Genentech also includes strategic assessment of key and novel technologies, as well as inter partes review and patent litigation support and advisement.

Juno Therapeutics has continuously relied on Dr. Polizzi for patent strategy and prosecution. Juno is one of the best-funded start-ups in biotechnology history. It went on to become a publicly traded company in 2014, and ultimately was acquired by Celgene in 2018 for $9 billion; the strength of the patent portfolio that Dr. Polizzi crafted helped drive the valuation for the deal. She led the IP team on the acquisition.

Celgene calls on Dr. Polizzi for its patent strategy, drafting, and IP due diligence matters. She worked with Abraxis BioScience for many years in a similar capacity to help develop the IP position for the highly successful cancer drug, Abraxane. Dr. Polizzi then counseled the company through its $2.9 billion acquisition by Celgene Corporation, including providing significant IP strategy and due diligence counseling. This IP platform was a major component of the valuation of the company. She was subsequently engaged by Celgene following the acquisition.

Medivation has turned to Dr. Polizzi as trusted outside patent counsel for more than a decade. She created the company’s initial patent strategy and portfolio. Dr. Polizzi also oversees additional promising drug candidates in Medivation’s pipeline. She led the IP due diligence team for Medivation’s acquisition of BioMarin’s phase III cancer drug, talazoparib, for $410 million upfront with another $160 million in milestones. She also led the IP due diligence for Medivation’s $14 billion acquisition by Pfizer in 2016. She continues to provide strategy and prosecution counsel on Medivation’s patent portfolio following the acquisition.
